Take this quiz to test your knowledge of living things. What are usually less than 6 mm long, have six legs like an insect, but are not insects? They come in various colors and shapes and live everywhere on Earth, including Antarctica. These tiny creatures can survive on the tallest mountains, in caves, underground, in deserts, grasslands, and forests. The class Collembola includes more than 9,000 species. They can “fly” without wings and provide beneficial services for agriculture. What are they? They are springtails.
They are called “springtails” because they can “spring” into the air so fast that their motion can only be captured at 10,000 frames per second. That helps them quickly escape predators or change locations. Springtails accomplish this Olympic-style feat with a spring-loaded appendage called a furcula on their underside. You could think of it as a lever that stores elastic energy the springtail can release when needed. They keep the furcula tucked under their bodies when not in use, but at any moment they can release it and propel themselves forward and upward.
Springtails thrive in moist locations such as soil, leaves, and rotting wood. They shed their outer shells in warm temperatures, reducing their body size by 30% and giving them a survival advantage. Some springtail species are considered pests; however, most springtails benefit agriculture. Mycorrhizal fungi have a beneficial symbiotic relationship with plant roots. Springtails collect mycorrhizal fungi spores and spread them to other locations, benefiting more plants.
Not only do springtails transport beneficial fungi, but they also eat the spores of pathogenic fungi and the damaging vegetative parts of fungi called mycelia. Through these functions, springtails play a crucial role in controlling plant and fungal diseases. Plant scientists have realized that springtails can be integrated into greenhouses to limit fungal growth. These seemingly insignificant creatures benefit humans.
The next time you see tiny creatures in leaf matter or rotting logs launch themselves into the air, instead of wondering “what are they,” you will know that they are springtails. You will also know they are some of the planet’s most beneficial creatures, playing a role in the marvelous web of life. It is evident that a wise Designer created the system.
